Each square below represents one whole. What percent is represented by the shaded area?

76%

There are 50 total squares and 38 are shaded.

38/50 =

76%

The answer to your question is 52

Step-by-step explanation:

Data

Percent of shaded area = ?

Process

1.- Count the numbers of squares in the first square

Number of squares = 5 x 5

                                 = 25

2.- Count the number of shaded squares in the second square

Number of squares = 13

3.- Calculate the percent of shaded squares using proportions

                    25 squares 100%

                      13 squares  x

                           x = (13 x 100) / 25

                           x = 1300 / 25

                           x = 52%      

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a
